CONCORD — Boston Salads and Provisions Company, Inc., a Boston establishment, is recalling approximately 223,000 pounds of ready-to-eat chicken salad products due to possible contamination with Listeria monocytogenes according to the U.S. Department of Agriculture’s (USDA’s) Food Safety and Inspection Service (FSIS).

The products were sold in local New Hampshire convenience stores including Mr. Mikes in Dover, Exit 3 Travel Stop in Portsmouth, Phillips Academy Grill in Exeter and Dover Paint and Varnish.

The products were produced between Aug. 23 and Oct. 14 and shipped to wholesalers for further distribution to retail locations in Massachusetts and New Hampshire. The New Hampshire Department of Health and Human Services (DHHS) is not aware of any illnesses in the state related to this recall.

Case labels or packaging may bear the sell by dates ranging from “9/13/2013” through “11/4/2013” as well as the establishment number “P-17999” inside the USDA mark of inspection. Although product included in this recall may be expired, FSIS is concerned that some product may be frozen in consumer or retail freezers. The problem was discovered by routine sampling which led to further testing and confirmation of product contamination with Listeria. Additional recalls may occur as the

investigation continues.

A list of recalled products to date is available at the USDA’s Food Recall website at <URL destination="http://www.fsis.usda.gov/wps/portal/fsis/topics/recalls-and-public-health-alerts/recall-case-archive/archive/2013/recall-061-2013-release">http://www.fsis.usda.gov/wps/portal/fsis/topics/recalls-and-public-health-alerts/recall-case-archive/archive/2013/recall-061-2013-release

If consumers have any of these products at home they are advised to discard them immediately and not eat them.

“It is important that all consumers, including retailers who may purchase larger containers for redistribution, check their freezers for this product,” said Dr. José Montero, director of public health at DHHS. “We are going to be keeping a close eye on this situation and continue monitoring for affected products and possible cases of illness. We will keep the

public informed of any new developments.”

Infection with listeriosis can produce such symptoms as fever, muscle aches, and sometimes nausea and vomiting. If the infection spreads to the central nervous system, symptoms can include headache, stiff neck, confusion, loss of balance, or convulsions. Listeriosis can be treated with antibiotics, so anyone who suspects they may have the illness should contact their health care provider.
